Abstract

A tubular anchor may have a polygonal cross-sectional configuration with flat outer side surfaces areas connected by a plurality of outer corner portions. A passage through the anchor may be formed by flat inner side surfaces interconnected by inner corner portions. A suture is inserted through the passage. A concentrated force may be applied against a limited area on a trailing end of the anchor to rotate the anchor to move an outer corner portion of the anchor into engagement with body tissue. The suture may engage an inner corner portion of the anchor. The suture may be inserted through a plurality of anchors and the anchors moved through a tubular member into the body tissue under the influence of force transmitted from a trailing anchor to a leading anchor. When the leading anchor is moved into the body tissue, it is rotated under the influence of force applied against a trailing end of the leading anchor. If desired, two anchors may be interconnected. A groove may advantageously be provided along the leading end and side of an anchor to receive the suture.

BACKGROUND OF THE INVENTION

The present invention relates to a new and improved anchor and to a new and improved method of using one or more anchors to secure a suture in body tissue.

A known anchor and method of securing a suture in body tissue is disclosed in U.S. Pat. No. 5,041,129 issued Aug. 20, 1991. This patent discloses the use of a hollow outer needle or tube in which an anchor and pusher tube are received. A suture extends through the pusher tube and anchor. Force is applied against a trailing end of the anchor by the pusher tube to move the anchor through the hollow outer needle or tube into body tissue. Other known anchors for use in securing a suture in body tissue are disclosed in U.S. Pat. No. 5,176,682 issued Jan. 5, 1993, U.S. Pat. No. 4,968,315 issued Nov. 6, 1990 and U.S. Pat. No. 4,741,330 issued May 3, 1988.

SUMMARY OF THE INVENTION

An improved suture anchor has a polygonal cross-sectional configuration with an outer side which is formed by a plurality of flat side surface areas which are interconnected by outer corner portions. The anchor has a passage formed by a plurality of flat inner side surface areas which are interconnected by a plurality of inner corner portions. A suture is engageable with one of the inner corner portions to urge an outer corner portion of the anchor into engagement with body tissue. A groove may be provided in the end and/or outer side of the anchor to receive the suture.

A plurality of anchors having the configuration of the improved anchor described above or a different configuration may be used to anchor a suture. When a plurality of anchors are used, the suture is inserted through each of the anchors and the anchors are sequentially moved into the body tissue. As a leading anchor is moved into the body tissue, the suture is tensioned to move a corner portion on the leading anchor into engagement with the body tissue. A connector may be provided between each anchor.

DESCRIPTION OF SPECIFIC PREFERRED EMBODIMENTS OF THE INVENTION

Anchor

An anchor 10 (FIG. 1) constructed in accordance with one of the features of the present invention may be used to secure a suture 12 in hard or soft body tissue. The anchor 10 has a tubular wall 13 with an outer side 14 and an inner side 16. The inner side 16 defines a passage 18 which extends through the anchor 10.

The outer side 14 of the tubular wall 13 has a polygonal cross-sectional configuration. Thus, the outer side 14 of the anchor 10 includes a plurality of longitudinally extending outer corner portions 22, 24, and 26. The outer corner portions 22, 24 and 26 are linear and interconnect a plurality of flat rectangular outer side surface areas 28, 30, and 32.

In the specific preferred embodiment of the anchor 10 illustrated in FIG. 1, the tubular wall 13 has an equilateral triangular cross-sectional configuration and forms a hollow prism. Therefore, the angles between the outer side surface areas 28, 30 and 32 at each of the corner portions 22, 24 and 26 is the same, that is, an angle of 120°. It should be understood that the outer side 14 of the anchor 10 could have a different configuration if desired.

For example, the outer side 14 of the anchor 10 could have a cross-sectional configuration corresponding to the configuration of a segment of a circle. An anchor 10 with an outside surface with such a configuration would have a pair of flat rectangular outer side surface areas. These surface areas would be interconnected by a corner portion. An arcuate surface area would extend between the flat outer side surface areas at a location opposite from the corner portion.

The inner side 16 of the anchor 10 has a polygonal cross-sectional configuration which corresponds to and is aligned with the polygonal outer side 14 of the anchor. The inner side 16 of the anchor 10 defines open ends of the passage 18 which extends through the anchor. Thus, the inner side 16 of the anchor has longitudinally extending inner corner portions 40, 42, and 44. The inner corner portions 40, 42 and 44 are linear and are aligned with and extend parallel to the outer corner portions 22, 24, and 26 and to a longitudinal central axis of the anchor 10.

In addition, the inner side 16 of the anchor 10 includes flat rectangular inner side surface areas 48, 50, and 52 which are interconnected by the inner corner portions 40, 42 and 44. The inner side surface areas 48, 50 and 52 extend parallel to and are spaced equal distances from the outer side surface areas 28, 30 and 32. The inner side 16 has a triangular cross-sectional configuration and is aligned with the outer side 14. Thus, the inner side 16 has a longitudinal central axis which is coincident with a longitudinal central axis of the outer side 14.

It is contemplated that the inner side 16 and outer side 14 could have different configurations. For example, the inner side 16 could be formed with a cross-sectional configuration which corresponds to the configuration of a circle or a segment of a circle. If desired, the inner side 16 could be formed as an almost complete cylinder with a radially extending corner portion which has a circumferential extent of, for example, 40° of the inner side.

In the embodiment of the anchor 10 illustrated in FIG. 1, the tubular wall 13 has three side walls 56, 58 and 60 which are of the same size. The side walls 56, 58 and 60 form rectangular sections of the tubular wall 13. However, it should be understood that the side walls 56, 58 and 60 could have a different configuration and that a greater or lesser number of side walls could be provided if desired.

In one specific embodiment of the anchor 10, the anchor had the configuration illustrated in FIG. 1 and was formed of stainless steel to ASTM designation F-138-86 specification. This specific embodiment of the anchor 10 had a length of 3.10 millimeters. Each of the rectangular side walls 56, 58 and 60 had a width of 1.83 millimeters. The side walls 56, 58 and 60 had a thickness of 0.5 millimeters. The outer corner portions 22, 24 and 26 had a radius of 0.3 millimeters and the inner corner portions 40, 42 and 44 had a radius of 0.15 millimeters.

In another specific embodiment of the invention, the anchor 10 was also formed of stainless steel having an ASTM designation F-138-86 specification. This embodiment of the anchor had a length of 7.2 millimeters. Each of the rectangular side walls 56, 58 and 60 had a width of 1.83 millimeters. The side walls had a thickness of 0.5 millimeters. Both of the specific foregoing examples of the anchor 10 had the hollow prism-shaped configuration illustrated in FIG. 1.

It should be understood that the foregoing specific dimensions and materials for specific examples of the anchor 10 have been set forth herein for purposes of clarity of description. It is contemplated that the anchor 10 could be made with dimensions which are different than the specific dimensions set forth above. However, it is believed that it may be advantageous to make the anchor 10 with a length of from 2 to 8 millimeters and a width of 1.0 to 2.5 millimeters. Of course, the specific dimensions of the anchor 10 can be varied depending upon the environment in which the anchor is to be utilized to secure a suture 12.

In accordance with another of the features of the invention, the anchor 10 is installed in body tissue in an orientation in which one of the outer corner portions 22, 24 or 26 is embedded in body tissue by force applied against an adjacent inner corner portion 40, 42 or 44 by the suture 12. Force applied by the suture 12 against one of the inner corner portions 22, 24 or 26 of the anchor 10 presses the flat outer side surface areas which are interconnected by the embedded corner portion against the body tissue. Thus, if the suture 12 applies force against the inner corner portion 40, the outer corner portion 22 becomes embedded in the body tissue and the flat outer side surface areas 28 and 32 are pressed against the body tissue.

The outer corner portions which are spaced from the embedded outer corner portion 22, 24 or 26 cooperate with the body tissue to stabilize the anchor 10 and hold it against sidewise movement. Parallel flat end surfaces 66 and 68 on the anchor 10 extend perpendicular to the outer side surfaces 28, 30 and 32 and cooperate with the body tissue to retain the anchor against axial movement relative to the body tissue. The cooperation between the outer corner portions 22, 24 and 26 and outer side surfaces 28, 30 and 32 with the body tissue securely retains the anchor 10 in place in the body tissue.

Installation Apparatus

When the anchor 10 is to be installed in human body tissue, the anchor may be pushed directly into the body tissue or into a recess may be formed in the body tissue to receive the anchor. The anchor 10 may be installed in either hard or soft body tissue. In FIGS. 2, 4, 5 and 6, the anchor 10 is to be installed in bone 72 in a human body. The bone 72 includes a compact outer layer 74 and a more porous cancellous tissue 76 which is surrounded by the compact outer layer.

A cylindrical recess or cavity 78 may be formed in the bone tissue to receive the anchor 10 in the manner illustrated in FIG. 2. It should be understood that the anchor 10 may be used with soft tissue rather than the hard tissue of the bone 72. It should also be understood that, if desired, the formation of the recess or cavity 78 may be omitted.

A tubular guide member 82 (FIGS. 2-6) is inserted into the recess 78 (FIG. 2). Although the tubular guide member 82 could have many different configurations, the illustrated guide member 82 is cylindrical and is inserted through a circular opening 84 to the recess 78. The guide member 82 is inserted through the compact outer layer 74 of bone tissue. A circular open inner end 86 of the guide member 82 is disposed immediately below (as viewed in FIG. 2) the inner side of the compact outer layer 74 of bone tissue 72.

The tubular guide member 82 has a cylindrical outer side surface 88 with a diameter which is substantially the same as the diameter of the cylindrical recess 78 and the circular opening 84 to the recess. Therefore, the bone tissue 82 firmly engages the outer side surface 88 of the guide member 72 to hold the guide member in position relative to the recess 78. The recess 78 extends inward past the lower (as viewed in FIG. 2) end 86 of the guide member 82 for a distance which is at least as great as the length of the anchor 10, that is at least as great as the distance from the end surface 66 to the end surface 68 (FIG. 1) of the anchor 10.

The tubular guide member 82 has a cylindrical inner side surface 92 (FIG. 3). When the anchor 10 is to be installed in the bone tissue 72, the anchor is positioned in the guide member 82 with the end surface 66 on the anchor leading (FIG. 2) and the end surface 68 on the anchor 10 trailing. The outer corner portions 22, 24 and 26 of the anchor 10 are disposed in engagement with the inner side surface 92 (FIG. 3) of the guide member 82 at equally spaced increments (approximately 120°) about the inner side surface of the guide member. A longitudinal central axis of the anchor 10 is coincident with a longitudinal central axis of the guide member 82.

The outer side surface areas 28, 30 and 32 (FIG. 3) of the anchor 10 are spaced from the inner side surface 92 of the guide member 82. The outer side surface areas 28, 30 and 32 extend parallel to a longitudinal central axis of the guide member 82. The outer side surface areas 28, 30 and 32 on the anchor 10 cooperate with the inner side surface area 92 on the guide member 82 to form a plurality, of channels 96, 98 and 100 between the anchor 10 and the inner side surface 92 of the guide member 82. The channels 96, 98 and 100 extend axially along the length of the anchor 10.

A portion 104 (FIG. 2) of the suture 12 extends downward (as viewed in FIG. 2) through the upper portion of the guide member 82 into the passage 18 in the anchor 10. A relatively short portion 106 of the suture 12 extends across the leading end surface 66 of the anchor 10. A second relatively long portion 108 of the suture 12 extends upward along the outer side surface area 32 of the anchor 10 through the channel 100. The relatively long portions 104 and 108 of the suture 12 extend from the guide member 82 to a location offset to one side of the recess 78 in the bone tissue 72.

Once the anchor 10 has been inserted into the tubular guide member 82 in the manner shown in FIGS. 2 and 3, a hollow cylindrical pusher member 112 (FIG. 2) is inserted into the guide member 82 through an open upper or outer end of the guide member. The pusher member 112 extends through the open upper or outer end of the guide member 82. The distance to which the pusher member 112 extends into telescopic engagement with the guide member 82 can be varied by moving the pusher member axially relative to the guide member. Although the pusher member 112 could have a configuration which is different than the cylindrical configuration of the guide member 82, it is preferred to utilize a pusher member having the same configuration as the guide member.

The suture 12 extends through a cylindrical passage 114 formed in the tubular pusher member 112. Thus, the portion 104 of the suture 12 extends into the pusher member 112 from a location offset to one side of the recess 78 in the bone tissue 72. The portion 104 of the suture 12 extends through the passage 114 in the pusher member 112 to the passage 18 in the anchor 10. The portion 106 of the suture 12 extends across the leading end 66 of the anchor 10.

The portion 108 of the suture 12 extends upward through the channel 100 along the outer side of the anchor 10 (FIGS. 2 and 3). The portion 108 of the suture 12 then extends through an open lower or inner end portion 116 (FIG. 2) of the pusher member 112 into the passage 114 in the tubular pusher member. The portion 108 of the suture 12 then extends from the open upper end of the pusher member to a location which is offset to one side of the recess 78. A surgeon can manually grip the suture 12 adjacent to an open upper end of the pusher member 112.

The pusher member 112 has a cylindrical outer side surface 122 which telescopically engages the cylindrical inner side surface 92 of the guide member 82. The cylindrical outer side surface 122 of the pusher member 112 has a diameter which is just slightly less than the diameter of the cylindrical inner side surface 92 of the guide member 82. Therefore, the pusher member 112 can slide freely along the inner side surface 92 of the guide member 82 while the guide member holds the inner side surface of the cylindrical pusher member in alignment with the longitudinal central axis of the anchor 10 (FIG. 2). Thus, the cylindrical inner side surface 92 of the guide member 82 engages the outer corner portions 22, 24 and 26 of the anchor 10 to guide movement of the anchor and engages the outer cylindrical side surface 122 of the pusher member 112 to guide movement of the pusher member.

The open end portion 116 of the pusher member 112 is axially tapered to enable the pusher member 112 to apply a concentrated force against the trailing end surface 68 (FIG. 2) of the anchor 10. Thus, the pusher member 112 has a lower (as viewed in FIG. 2) end surface 126 which is skewed at an acute angle to a longitudinal central axis of the pusher member (FIG. 4). In addition, the pusher member 112 has a flat end surface 128 which engages the trailing end surface 68 of the anchor 10.

The flat end surface 128 has a length and width which enables it to engage the trailing end surface 68 of the anchor regardless of the orientation of the pusher member 112 relative to the trailing end surface 68 of the anchor. This enables the pusher member 112 to engage the trailing end surface 68 of the anchor at a location adjacent to one of the outer corner portions 22, 24 or 26 (FIG. 2) of the anchor and/or to engage the anchor at a location adjacent to one of the outer side surface areas 28, 30 or 32 of the anchor.

The tapered configuration of the open end portion 116 of the pusher member 112 results in the pusher member applying a concentrated force against the trailing end surface 68 of the anchor at a location which is offset from the central axis of the anchor. Since the force applied by the pusher member 112 to the trailing end surface 68 of the anchor is offset from the central axis of the anchor 10, a torque is applied to the anchor which tends to rotate the anchor about an axis extending through the location where the end portion 116 of the pusher member 112 engages the trailing end surface 68 of the anchor.

When the anchor 10 is in the guide member 82 (FIGS. 2 and 3), the outer corner portions 22, 24 and 26 of the anchor member engage the cylindrical inner side surface 92 of the guide member 82 to retain the anchor against rotational movement under the influence of the concentrated force applied against the trailing end surface 68 of the anchor by the pusher member 112. Thus, the cylindrical inner side surface 92 of the guide member 82 cooperates with the anchor 10 to retain the longitudinal central axis of the anchor 10 coincident with the longitudinal central axis of the guide member. In addition, the cylindrical inner side surface 92 of the guide member 82 cooperates with a cylindrical outer side surface 132 of the pusher member 112 to retain the pusher member in an orientation in which the longitudinal central axis of the pusher member is coincident with the longitudinal central axis of the guide member 82.

In the embodiment of the invention illustrated in FIGS. 2 and 3, the guide member 82 and the pusher member 112 both have cylindrical configurations. However, it is contemplated that the pusher member 112 and guide member 82 could have different configurations. For example, the guide member 82 and the pusher member 112 could both have triangular cross-sectional configurations. If desired, the guide member 82 could have a circular cross-sectional configuration and the pusher member 112 could have a triangular cross-sectional configuration.

Installation Procedures

When the anchor 10 is to be installed in body tissue, which may be either hard or soft tissue, the suture 12 is inserted through the passage 18 (FIG. 2) in the anchor 10. The relatively long portion 104 of the suture 12 extends through the passage 18 to the portion 106 of the suture. The portion 106 of the suture extends across the end surface 66 of the anchor. The portion 108 of the suture extends along the outer side 13 of the anchor 10. In FIG. 2, the portion 108 of the suture 12 extends along the outer side surface area 32. However, the portion 108 of the suture 12 could extend along any one of the outer side surface areas 28, 30 or 32.

Once the suture 12 has been inserted through the passage 18 in the anchor 10, the anchor is inserted into the guide member 82. As this is done, the outer corner portions 22, 24 and 26 (FIG. 3) of the anchor engage the inner side surface 92 of the guide member 82 to position the anchor relative to the guide member. The portion 108 of the suture 12 extends through the channel 100 formed between the outer side surface area 32 on the anchor 10 and the inner side surface 92 of the guide member 82. The guide member 82 retains the anchor 10 in an orientation in which a longitudinal central axis of the anchor is coincident with a longitudinal central axis of the guide member.

Either before or after the anchor 10 is inserted into the guide member 82, the suture 12 is inserted through the open ended passage 114 (FIG. 2) in the pusher member 112. After the anchor 10 has been inserted into the guide member 82, the pusher member 112 is inserted into the guide member. The open leading end portion 116 of the pusher member 112 is moved into engagement with the trailing end surface 68 of the anchor 10.

The pusher member 112 is pressed against the trailing end surface 68 of the anchor 10 to move the anchor through the guide member 82 toward the recess 78 in the bone 72. As this is occurring, the anchor 10 and pusher member 112 may rotate relative to each other and to the guide member 82 about their coincident central axes. However, the inner side surface 92 of the guide member 82 engages the corner portions 22, 24, and 26 of the anchor 10 to retain the anchor against rotational movement about an axis extending transversely to and offset from the longitudinal central axis of the anchor. Thus, the corner portions 22, 24 and 26 on the anchor 10 slide along the inner side surface 92 of the guide member 82 to maintain the longitudinal central axis of the anchor coincident with the longitudinal central axis of the guide member.

A concentrated force is applied against the trailing end surface 68 of the anchor by the tapered end portion 116 of the pusher member 112. The pusher member 112 applies the concentrated force against the anchor 10 at a location which is offset to one side of the longitudinal central axis of the anchor 10. Thus, the flat end surface 128 on the tapered end portion 116 of the pusher member 112 engages the anchor 10 at a trailing end of one of the corner portions 22, 24 or 26 and/or a trailing end of one of the sidewalls 56, 58 or 60. The tapered end portion 116 of the pusher member 112 has a radial thickness which is sufficient to enable the tapered end portion to span one of the channels 96, 98 or 100 (FIG. 3) to engage the trailing end of a sidewall 56, 58 or 60 at a location spaced from the corner portions 22, 24 and 26 of the anchor 10.

Engagement of the tapered end portion 116 of the pusher member 112 with the trailing end of the anchor 10 at a location offset to one side of the longitudinal central axis of the anchor results in the application of torque to the anchor. This torque tends to rotate the anchor about an axis extending through the location where the tapered end portion 116 of the pusher member 112 engages the trailing end surface 68 on the anchor. The outer corner portions 22, 24 and 26 of the anchor 10 engage the inner side surface 92 of the guide member 82 to hold the anchor against rotation under the influence of the torque applied to the anchor by the pusher member 112 as the anchor moves through the guide member.

As the pusher member 112 moves downward (as viewed in FIG. 2) relative to the guide member 82, the anchor 10 is pushed downward in the guide member. As this occurs the anchor 10 pulls the suture downward. Thus, force is transmitted from the leading end surface 66 of the anchor 10 to the portion 106 of the suture 12 to pull the suture into the pusher member 112 and guide member 82.

As the anchor continues to move downward (as viewed in FIG. 2), the leading end of the anchor and the portion 106 of the suture 12 emerge from the open lower end 86 of the guide member 82 into the recess 78. As the anchor 10 moves through the open lower (as viewed in FIG. 2) end portion of the guide member 82, the suture 12 is tensioned to apply force against the leading end surface 66 of the anchor. The surgeon pulls on the portions 104 and 108 of the suture 12 to tension the suture. This force pulls the anchor upward (as viewed in FIG. 2) against the pusher member 112.

As the suture is tensioned and the trailing end portion of the anchor 10 begins to move out of the guide member 82, the suture slides along one of the inner side surface areas 48, 50 or 52 on the anchor into one of the inner corner portions 40, 42 or 44. This tends to rotate the anchor about its longitudinal central axis relative to the pusher member 112 to move one of the side walls 56, 58 or 60 on the anchor into alignment with the tapered end portion 116 of the pusher member 112. As this occurs, the force applied by the tapered end portion 116 of the pusher member 112 becomes concentrated at the trailing end portion of one of the side walls 56, 58 or 60 of the anchor.

For example, the anchor 10 rotates about its central axis from the position shown in FIG. 2 to the position shown in FIG. 4. When this occurs, the surface 126 on the tapered leading end portion 116 of the pusher member 112 engages the trailing end of the side wall 58 (FIG. 1) of the anchor 10. This results in the force applied by the pusher member 112 being concentrated at a location which is opposite from the outer corner portion 22 of the anchor. By concentrating the force applied against the trailing end surface 68 of the anchor by the pusher member 112 at a location opposite from the corner portion 22, the torque applied to the anchor 10 by the pusher member 112 tends to rotate the anchor in a clockwise direction, as indicated by the arrow 140 in FIG. 4.

Simultaneously with rotation of the anchor 10 about its central axis, the tension in the suture 12 applies force against the leading end surface 66 of the anchor. The force applied against the leading end 66 of the anchor 10 by the suture 12 pulls the trailing end 68 of the anchor back or upward (as viewed in FIG. 4) toward the tapered leading end portion 116 of the pusher member 112. Therefore, the tension in the suture 12 tends to further rotate the anchor 10 in a counterclockwise direction (as viewed in FIG. 4), in the manner indicated schematically by the arrow 140. The inner corner portion 40 of the anchor 10 holds the suture 12 against sidewise movement relative to the anchor and concentrates the force applied by the suture to the anchor at the inner corner portion of the anchor.

Under the combined influence of the concentrated force applied against the trailing end surface 68 of the anchor 10 by the pusher member 112 and the force applied against the inner corner portion 40 of the anchor adjacent to the leading end surface 66 by the suture 12, the anchor is rotated into the cancellous bone tissue 76, in the manner indicated schematically by the arrow 140 in FIG. 4. Thus, the anchor 10 is rotated about an axis which extends perpendicular to and is offset from the central axis of the guide member 82. The axis about which the anchor 10 rotates extends through the location where the leading end surface 128 on the pusher member 112 engages the trailing end surface 68 on the anchor 10. As this occurs, the pusher member 112 continues to move axially downward (as viewed in FIG. 4) in the guide member 82 into the recess 78. The anchor 10 continues to rotate about the axis extending through the location where the end surface 128 on the pusher member 112 engages the end surface 68 on the anchor 10 until the surface 68 on the anchor moves into abutting engagement with the sloping end surface 126 on the pusher member 112.

The combination of concentrated force pushing against the trailing end surface 68 of the anchor on one side of the longitudinal central axis of the anchor and a pulling force applied against the leading end surface 66 at a corner portion of the anchor on the opposite side of the longitudinal central axis of the anchor results in a substantial counterclockwise (as viewed in FIG. 4) torque which causes the anchor to rotate against the resistance provided by the soft cancellous tissue 76 of the bone 72. This results in the anchor 10 moving from the upright orientation shown in FIG. 2 through the orientation shown in FIG. 4 toward an orientation in which the trailing end surface 68 on the anchor 10 engages the sloping end surface 126 on the pusher member 112.

When the trailing end surface 68 on the anchor 10 engages the sloping end surface 126 (FIG. 4) on the pusher member 112, the central axis of the anchor extends perpendicular to the sloping end surface 126 and is skewed at an angle of 45° to the central axis of the guide member 82. The pusher member 112 is then withdrawn into the guide member 82. As the pusher member 112 is moved axially upward as viewed in FIG. 4 into the guide member 82, the force applied by the suture 12 against the leading end 66 of the anchor 10 continues in counterclockwise rotation of the anchor. The force applied against the leading end portion 66 of the anchor by the suture 12 presses the trailing end portion 68 of the anchor against the left (as viewed in FIGS. 4 and 5) side surface of the recess 78.

Continued pulling or tensioning of the suture 12 results in the outer corner portion 22 of the anchor 10 being pulled upward toward the inner or lower (as viewed in FIG. 5) end surface 86 of the guide member 82. As this occurs, the force transmitted from the suture 12 to the anchor 10 pulls the trailing end of the anchor toward the left, as viewed in FIG. 4. Thus, the anchor 10 is first moved toward the right (as viewed in FIG. 4) of the central axis of guide member 82 under the combined influence of force applied against the anchor by the pusher member 112 and the suture 12. The pusher member 112 is then slowly withdrawn and, simultaneously therewith, the anchor 10 is moved toward the right (as viewed in FIGS. 4 and 5) under the influence of force applied against the anchor by tension in the suture 12. The suture 12 is tensioned by the surgeon when he or she manually pulls on the suture.

The force on the anchor 10 causes it to move to the substantially horizontal orientation shown in FIGS. 5 and 6. At this time, the longitudinal central axis of the anchor 10 and the outer corner portions 22, 24 and 26 of the anchor extend perpendicular to the coincident longitudinal central axes of the guide member 82 and pusher member 112. The tension force in the suture 12 pulls the outer corner portion 22 of the anchor 10 upward toward the lower end of the guide member 82.

As this is occurring, the outer corner portion 22 of the anchor 10 becomes embedded in the relatively soft cancellous bone tissue 76 (FIG. 6). In addition, the flat outer side surface areas 28 and 32 press against the cancellous bone tissue to stabilize the anchor 10. The outer corner portions 24 and 26 opposite from the corner portion 22, cooperate with the cancellous bone tissue 76 to further stabilize the anchor and retain the anchor 10 against movement relative to the body tissue 72.

The polygonal configuration of the anchor 10 results in the anchor being retained against movement relative to the body tissue 72. Thus, the outer corner portions 22, 24 and 26 of the anchor 10 become embedded in the body tissue 72. The flat outer side surface areas 28 and 32 of the anchor are pressed against the body tissue to further stabilize the anchor.

With the passage of time, the body tissue tends to grow into the recess 78 and the space caused by moving the anchor 10 from the position shown in FIG. 2 through the position shown in FIG. 4 to the position shown in FIG. 5. As this occurs, the body tissue grows into engagement with the flat outer side surface area 30 of the anchor to further stabilize the anchor. Although the anchor 10 is very stable in the body tissue 72, the anchor can be removed from the body tissue in the same manner as is disclosed in the aforementioned U.S. patent application Ser. No. 08/062,295 filed May 14, 1993 of which this application is a continuation-in-part.

Anchor Guide and Pusher Members—Second Embodiment

In the embodiment of the invention illustrated in FIGS. 1-6, the anchor 10 is randomly oriented relative to the guide member 82. As the anchor 10 emerges from the guide member 82, the force applied against the anchor by tensioning the suture 12 results in the suture moving along an inner side surface area 48, 50 or 52 of the anchor into engagement with one of the inner corner portions 40, 42 and 44. As this occurs, the anchor moves relative to the pusher member 112 to an orientation in which the tapered end portion 116 of the pusher member 112 applies a concentrated force against a portion of the anchor opposite from the inner corner portion engaged by the suture 12. For example, if the suture 12 engages the inner corner portion 40, as shown in FIG. 4, the pusher member 112 applies a concentrated force against the side wall 58 adjacent to the outer corner portions 24 and 26.

It is contemplated that it may be desired to orient the anchor 10 relative to the body tissue 72 before the anchor begins to move into the recess 78. In the embodiment of the invention illustrated in FIGS. 7-10, the tubular guide member is constructed so as to retain the anchor in a selected orientation relative to the guide member as the anchor moves axially through the guide member. In addition, the pusher member is constructed so as to apply a concentrated force against a selected portion of the anchor. Since the embodiment of the invention illustrated in FIGS. 7-10 is generally similar to the embodiment of the invention illustrated in FIGS. 1-6, similar numerals will be utilized to designate similar components, the suffix letter “a” being associated with the numerals of FIGS. 7-10 to avoid confusion.

A tubular guide member 82 a (FIG. 7) has a cylindrical outer side surface 88 a and a cylindrical inner side surface 92 a. In addition, the guide member 82 a has a linear locating rib 142 which orients the anchor 10 a in the guide member 82 a. The locating rib 142 extends axially along the inner side 92 a of the guide member 82 a for the entire length of the guide member. A longitudinal central axis of the locating rib 142 extends parallel to a longitudinal central axis of the guide member 82 a.

The locating rib 142 has a flat inwardly facing locating surface 144. The flat locating surface 144 is disposed in a plane which forms a chord to the cylindrical inner side surface 92 a of the guide member 82 a. The plane in which the locating surface 144 is disposed, extends parallel to the longitudinal central axis of the guide member 82 a. The locating surface 144 has an axial extent which is the same as the axial extent of the guide members 82 a.

When an anchor 10 is in the orientation shown in FIG. 7, the locating surface 144 engages the flat outer side surface area 30 a on the anchor 10 a to position the anchor in a predetermined orientation relative to the guide member 82 a. The corner portion 22 a of the anchor 10 a is disposed diametrically across from the locating surface 144. Of course, the anchor 10 a could be positioned relative to the tubular guide member 82 a with the flat locating surface 144 in abutting engagement with any one of the flat outer side surface areas 28 a, 30 a or 32 a on the anchor.

The corner portions 22 a, 24 a and 26 a (FIG. 7) of the anchor 10 a engage the cylindrical inner side surface 92 a of the guide member 82 a to hold the anchor 10 a in alignment with a longitudinal central axis of the guide member 82 a. The locating surface 144 engages the flat outer side surface area 30 a on the anchor 10 a to hold the anchor in a predetermined orientation relative to the longitudinal central axis of the guide member 82 a. Thus, the locating surface 144 engages the flat outer side surface 30 a on the anchor 10 a to prevent rotation of the anchor about its longitudinal central axis relative to the guide member 82 a. The longitudinal central axis of the anchor 10 a is coincident with the longitudinal central axis of the guide member 82 a.

The location of the anchor 10 a relative to the body tissue into which it is to be inserted can be selected by a surgeon before inserting the anchor. Thus, the outer corner portion 22 a of the anchor 10 a is diametrically across the guide member 82 a from the locating surface 144. At this time, the corner portion 22 a of the anchor 10 a has a longitudinal central axis which is located in a plane which contains the longitudinal central axis of the locating rib 142. Therefore, by selecting the orientation of the locating rib 142 relative to the body tissue, the surgeon can select the orientation of the outer corner portion 22 a of the anchor relative to the body tissue.

When the anchor 10 a is installed in body tissue to anchor the suture 12 a, in the manner shown in FIGS. 5 and 6 for the anchor 10, the longitudinal central axis of the corner portion 22 a of anchor 10 a is still disposed in the plane containing the parallel longitudinal central axes of the guide member 82 a and the locating rib 142. The longitudinal central axis of the anchor 10 a is also disposed in the plane containing the longitudinal central axes of the guide member 82 a and the locating rib 142. However, when the anchor 10 a is installed in body tissue, in the manner shown in FIGS. 5 and 6 for the anchor 10, the longitudinal central axes of the corner portion 22 a and anchor 10 a extend perpendicular to the parallel longitudinal central axes of the guide member 82 a and locating rib 142.

A pusher member 112 a (FIGS. 8 and 9) cooperates with the guide member 82 a to apply force against the anchor 10 a at locations which are opposite from the outer corner portion 22 a and are adjacent to opposite longitudinally extending side surfaces 146 and 148 (FIG. 7) on the locating rib 142. The side surfaces 146 and 148 extend perpendicular to the locating surface 144. The side surfaces 146 and 148 extend parallel to each other and are spaced apart by a distance which is substantially less than the distance between the corner portions 24 a and 26 a of the anchor 10 a.

The pusher member 112 a is a cylindrical tubular member having a tapered end portion 116 a (FIG. 8). The tubular pusher member 112 a has a radially extending slot 150 (FIG. 9) which extends throughout the length of the pusher member and receives the locating rib 142. Opposite side surfaces 151 and 152 of the slot 150 extend parallel to each other and engage opposite side surfaces 146 and 148 on the locating rib 142. Thus, the locating rib 142 cooperates with the slot 150 to orient the pusher member 112 a relative to the guide member 82 a. Since the anchor 10 a is also oriented relative to the guide member 82 a by the locating rib 142, the locating rib is effective to orient the pusher member 112 a relative to the anchor.

The pusher member 112 a has a tapered leading or lower (as viewed in FIG. 8) end surface 128 a which applies force against the anchor 10 a at locations adjacent to opposite sides of the locating rib 142 in the tubular guide member 82 a. The manner in which the end surface 128 a on the pusher member 112 a applies force against the anchor 10 a is indicated schematically in FIG. 7 by the arrows 154 and 156. The arrows 154 and 156 extend parallel to the longitudinal central axis of the locating rib 142 and to the longitudinal central axis of the anchor 10 a.

The pusher member force represented by the arrows 154 and 156 is applied against the trailing end surface area 68 a on the side wall 58 a (FIG. 7) of the anchor 10 a opposite from the outer corner portion 22 a. Thus, the pusher member 112 a applies a force which is concentrated against the same side wall 58 a of the anchor as is engaged by the locating surface 144 on the locating rib 142. This results in the pusher member 112 a applying force against the trailing end surface 68 a of the anchor 10 a at locations which are selected by selecting the orientation of the anchor in the guide member 82 a.

When the anchor 10 a is to be installed in body tissue, the tubular guide member 82 a is positioned in a selected orientation relative to the body tissue. Thus, the open lower end 96 a (FIG. 10) of the guide member 82 a is inserted into a recess in the body tissue, in the manner illustrated in FIG. 2 for the guide member 82, with the locating rib 142 at a location where it is desired to have the outer corner portion 22 a of the anchor 10 a embedded in the body tissue.

The suture 12 a (FIG. 10) is inserted through the central passage 18 a in the anchor 10 a. Thus, the portion 104 a of the suture 12 a extends through the passage 18 a in the anchor 10 a and the portion 108 a of the suture 12 a extends along the outer side surface 32 a of the anchor. The suture is also inserted through the central passage 114 a (FIG. 8) in the pusher member 112 a.

The anchor 10 a is then positioned in the guide member 82 a with the flat outer side surface area 30 a (FIG. 7) on the anchor in abutting engagement with the flat locating surface 144 on the locating rib 142. The portion 108 a of the suture will extend through the channel 100 a formed between the inner side surface 92 a of the guide member 82 a and the outer side of the anchor 10 a.

The pusher member 112 a is then inserted into the tubular guide member 82 a with the portions 104 a and 108 a of the suture 12 a extending through the cylindrical passage 114 a in the tubular pusher member. The locating rib 142 extends radially through the slot 150 formed in the pusher member 112 a. The side surfaces 151 and 152 of the slot 150 (FIG. 9) engage opposite side surfaces 146 and 148 on the locating rib 142). Engagement of the locating rib 142 with the slot 150 in the pusher member 112 a orients the pusher member 112 a relative to both the anchor 10 a and the guide member 82 a.

The lower or leading end surface 128 a (FIG. 8) on the pusher member 112 a engages the upper end surface of the side wall 58 a (FIG. 7) of the anchor 10 a adjacent to opposite sides of the locating rib 142. Thus, when the pusher member 112 a is pressed against the anchor 10 a, the end surface 128 a on the pusher member 112 a applies force against the trailing end surface 68 a of the anchor 10 a at the side wall 58 a, in the manner indicated by the arrows 154 and 156 in FIG. 7.

The force applied against the trailing end surface 68 a of the anchor 10 a by the pusher member 112 a moves the anchor axially downward (as viewed in FIG. 7) through the guide member 82 a until a leading end surface 66 a (FIG. 10) on the anchor emerges from the open lower (as viewed in FIG. 10) end 92 a of the guide member 82 a. During this movement of the anchor 10 a through the tubular guide member 82 a, both the anchor and the pusher member 112 a are maintained in a predetermined orientation relative to the guide member by the locating rib 142. The locating rib 142 cooperates with the pusher member 112 a and the anchor 10 a to retain them against rotation relative to each other about the central axis of the guide member 82 a.

As the anchor 10 a begins to emerge from the lower (as viewed in FIG. 10) end portion 86 a of the tubular guide member 82 a, the force applied against the trailing end surface 68 a of the anchor by the pusher member 112 a applies a torque to the anchor which tends to rotate the anchor in a counterclockwise direction (as viewed in FIG. 10). As this occurs, the suture 12 a is tensioned to apply a force against the inner corner portion 40 a of the anchor 10 a adjacent to the leading end surface 66 a of the anchor. The forces result in the anchor being rotated in a counterclockwise direction as viewed in FIG. 10.

Once the trailing end of the anchor 10 a has moved clear of the tubular guide member 82 a, the force applied against the leading end surface 66 a of the anchor 10 a by the portion 106 a of the suture 12 a moves the anchor 10 a toward the left (as viewed in FIG. 10). Therefore, the anchor 10 a moves to a position in which it extends diametrically across the open lower end portion 92 a of the guide member 82 a. This results in the anchor 10 a being installed in body tissue in a position similar to that shown for the anchor 10 in FIGS. 5 and 6.

Continued pulling or tensioning of the suture 12 a results in the corner portion 22 a of the anchor becoming embedded in the body tissue and the outer side surfaces 28 a and 32 a of the anchor applying force against the body tissue. At this time, the outer corner portions 24 a and 26 a cooperate with the body tissue to further stabilize the anchor 10 a. Once the anchor 10 a has been moved into position in the body tissue, both the guide member 82 a and the pusher member 112 a are withdrawn from the body tissue.

In the embodiment of the invention illustrated in FIGS. 7-10, the locating rib 142 positions the anchor relative to the guide member 82 a. However, it is contemplated that many different arrangements of locating surfaces could be provided on the guide member to locate the anchor relative to the guide member. For example, the guide member 82 a could be formed with a configuration corresponding to the configuration of a segment of a circle. If this was done, the portion 108 a of the suture 12 a would be disposed adjacent to the arcuate portion of the guide member while the opposite outer corner portion of the anchor would be engaged by the apex of the guide member. If desired, the guide member could have a polygonal cross-sectional configuration corresponding to the polygonal cross-sectional configuration of the anchor. If this is done, a groove in the guide member could be used as a channel to receive the portion 108 a of the suture 12 a.

Anchor—Second Embodiment

It is contemplated that during use of the anchor 10 of FIGS. 1-6, it may be desired to protect the suture 12 from engagement with surfaces in the environment in which the anchor is used. In the embodiment of the anchor illustrated in FIGS. 11 and 12, grooves are provided to receive the suture to protect the suture. Since the embodiment of the anchor illustrated in FIGS. 11 and 12 is generally similar to the embodiment of the invention illustrated in FIGS. 1-6, similar numerals will be utilized to designate similar components, the suffix letter “b” being associated with the numerals of FIGS. 11 and 12 to avoid confusion.

An anchor 10 b has outer corner portions 22 b, 24 b and 26 b which interconnect flat outer side surface areas 28 b, 30 b and 32 b. A central passage 18 b extends through the anchor. The anchor 10 b has the same configuration as the anchor 10 of FIG. 1.

In accordance with a feature of this embodiment of the invention, the anchor 10 b has a groove 162 (FIG. 11) in which the suture 12 b is received. The groove 162 has a longitudinally extending main portion 164 which is disposed inwardly from the flat outer side surface 32 b of the anchor 10 b. The main portion 164 of the groove 162 has a flat bottom surface 166 which extends parallel to the flat outer side surface area 32 b and extends between axially opposite ends of the anchor 10 b. The main portion 164 of the groove 162 receives the portion 108 b of the suture 12 b which extends along the outside of the anchor.

The main portion 164 of the groove 162 has a flat longitudinally extending side surface 170 which is disposed in a central portion of the flat outer side surface 32 b and a flat longitudinally extending side surface 172 which is disposed in a central portion of the outer corner portion 22 b (FIG. 12). This enables the portion 10 b (FIG. 11) of the suture 12 b to move from a position adjacent to the central portion of the flat outer side surface 32 b to the outer corner portion 22 b as the inner portion of the suture moves into engagement with the inner corner portion 40 b (FIG. 12) of the anchor 10 b. Thus, as the anchor 106 is rotated and moved into position relative to the end of the guide member in the manner shown in FIGS. 4 and 5 for the anchor 10, the portion 108 b of the suture 12 b will move sidewardly, that is in a direction transverse to the longitudinal central axis of the main portion 164 of the groove 162, into engagement with the longitudinally extending side surface 172 of the groove. This occurs as the portion of the suture which extends through the passage 18 b in the anchor 10 b moves into engagement with the inner corner portion 40 b of the anchor.

In addition, the groove 162 has an end portion 176 which extends transversely to the main portion 164 of the groove 162 and extends across the end surface 66 b of the anchor 10 b. The end portion 176 of the groove 162 extends from a central portion of an end of the side wall 60 b to the inner and outer corner portions 40 b and 22 b. The end portion 176 of the groove 162 receives the portion 106 b of the suture 12 b to protect the suture. Since the end portion 176 of the groove extends from the central portion of the side wall 60 b to the outer corner portion 22 b, the portion 106 b of the suture can move to a location extending between the inner corner portion 40 b and the outer corner portion 22 b as the anchor is moved from the orientation shown in FIG. 4 to the orientation shown in FIG. 5 for the anchor 10.

Although the groove 162 has been illustrated herein as having both the main portion 164 and the end portion 176, it is contemplated that the groove 162 could have either just the main portion 164 or the end portion 176 if desired. It is also contemplated that the groove 162 could have a configuration other than the configuration illustrated herein.

Plural Anchors

In the embodiment of the invention illustrated in FIGS. 1-6, a single anchor 10 is used to secure the suture 12 in body tissue. In the embodiment of the invention illustrated in FIGS. 13-16, a plurality of anchors are used to secure a suture in body tissue. Since the embodiment of the invention illustrated in FIGS. 13-16 is generally similar to the embodiment of the invention illustrated in FIGS. 1-6, similar numerals will be utilized to designate similar components, the suffix letter “c” being associated with the numerals of FIGS. 13-16 to avoid confusion.

In accordance with a feature of this embodiment of the invention, a pair of anchors 182 and 184 (FIG. 13) are used to secure a suture 12 c in body tissue. However, a greater number of anchors could be used if desired. The anchors 182 and 184 both have the same general construction as the anchor 10 of FIGS. 1-6. However, the trailing anchor 182 has a tapered leading end portion 186. If desired, the anchors 182 and 184 could have a construction which is different from the construction of the anchor 10.

The tapered leading end portion 186 of the trailing anchor 182 extends from an outer corner portion 22 c of the anchor 182 to an outer side surface 30 c on a side wall 58 c and to the corner portions opposite from the corner portion 22 c of the anchor 182. The outer side surface area 30 c has a flat rectangular configuration. The tapered leading end portion 186 of the anchor 182 includes a flat leading end surface 66 c which is disposed in a plane which is skewed at an acute angle to a trailing end surface 68 c. Other than having the tapered leading end portion 186, the construction of the anchor 182 is the same as the construction of the anchor 10 of FIGS. 1-6.

The leading anchor 184 has the same construction as the anchor 10 of FIGS. 1-6. Thus, the leading anchor 184 has a leading end surface 66 c which is parallel to the trailing end surface 68 c. The leading and trailing end surfaces 66 c and 68 c of the anchor 184 extend perpendicular to a longitudinal central axis of the suture.

Although it is preferred to use anchors 182 and 184 having the same configuration as the anchor 10 of FIGS. 1-6, the anchors 182 and 184 could have a configuration which is different than the configuration of the anchor 10. For example, the anchors 182 and 184 could have a cylindrical configuration or any of the other anchor configurations disclosed in the aforementioned U.S. patent application Ser. No. 08/062,295 filed May 14, 1993 of which this application is a continuation-in-part. However, the anchor corresponding to the anchor 182 and having any one of these constructions may be provided with a tapered leading end portion.

Although it is preferred to form the leading anchor 184 with a trailing end surface 68 c which extends perpendicular to the central axis of the anchor, the trailing end portion of the leading anchor 184 could be tapered in a manner similar to the tapered leading end portion 186 of the trailing anchor 182. If the trailing end portion of the anchor 184 is tapered, the leading end portion of the anchor 182 could extend perpendicular to the central axis of the anchor 182 or could be tapered in a manner similar to that shown in FIG. 13.

When the anchors 182 and 184 are to be used to secure the suture 12 c into bone 72 c or other body tissue, a cylindrical recess 78 c may be formed in the body tissue. A tubular cylindrical guide member 82 c is inserted into the recess 78 c in the manner illustrated in FIG. 13. Although the tubular guide member 82 c has the same construction as the guide member 82 of FIGS. 2-6, a guide member having a different construction could be used if desired.

The suture 12 c is inserted through central passages 18 c in the anchors 182 and 184. This results in the two anchors 182 and 184 being strung together on the suture 12 c. A portion 104 c (FIG. 13) of the suture 12 c extends through the central passage 18 c in the anchor 182 and through the central passage 18 c in the anchor 184. A portion 106 c of the suture 12 c extends across the leading end surface 66 c of the leading anchor 184. A portion 108 c of the suture 12 c extends along the outside of the two anchors 182 and 184.

After the anchors 182 and 184 have been strung on the suture 12 c, the anchors 182 and 184 are positioned in the tubular guide member 82 c. Corner portions of the anchors 182 and 184 engage a cylindrical inner side surface 92 c of the guide member 82 c. Thus, the corner portions of the anchors 182 and 184 engage the inner side surface 92 c of the guide member 82 c in the same manner as in which the corner portions 22, 24 and 26 of the anchor 10 engage the inner side surface 92 of the tubular guide member 82 (FIG. 3).

The anchors 182 and 184 are positioned in the cylindrical guide member 82 c with the corner portions of the anchors aligned with each other and with the anchors in a coaxial relationship with each other. The anchors 182 and 184 are also positioned in the guide member 82 c with the anchors in a coaxial relationship with each other and with the guide member. A knife edge end 190 of the tapered leading end portion 186 of the anchor 182 is disposed in engagement with the trailing end surface 68 c of the anchor 184 along the side wall 58 c of the anchor 184. The knife edge end 190 of the tapered leading end portion 186 of the anchor 182 has a configuration similar to the configuration of a cutting portion of a chisel. The knife edge end 190 extends along the side wall 58 c of the anchor 182 between corner portions at opposite ends of the side wall, that is, between corner portions corresponding to the corner portions 24 and 26 (FIG. 3) of the anchor 10. Thus, force is transmitted from the trailing anchor 182 to the leading anchor 184 along the entire width of the trailing end surface of the side wall 58 c of the anchor 184.

A cylindrical tubular pusher member 112 c is inserted into the guide member 82 c and applies force to the trailing end surface 68 c of the trailing anchor 182. The pusher member 112 c has a flat circular leading end surface 126 c which is disposed in a plane extending perpendicular to a longitudinal central axis of the pusher member 112 c. Thus, the pusher member 112 c of FIG. 13 does not have a tapered open end portion in the same manner as does the pusher member 112 of FIGS. 2 and 4. However, if desired, the pusher member 112 c could be provided with a tapered open end portion having a configuration similar to the configuration of the tapered open end portion 116 of the pusher member 112 (FIGS. 2 and 4).

The circular leading end surface 126 c of the pusher member 112 c engages the trailing end surface 68 c of the trailing anchor 182 at each of the three corner portions of the anchor. This results in the trailing anchor 182 being pushed straight down (as viewed in FIG. 13) by the pusher member 112 c. The pusher member 112 c does not apply torque to the trailing anchor 182. This is because the force applied to the trailing end surface 68 c of the anchor 182 by the pusher member 112 c is balanced about the central axis of the anchor.

Although the pusher member 112 c does not apply torque to the trailing anchor 182, the trailing anchor 182 is effective to apply torque to the leading anchor 184. This is because force is transmitted from the trailing anchor 182 through the tapered leading end portion 186 of the trailing anchor 182 to the leading anchor 184. The force transmitted from the trailing anchor 182 to the leading anchor 184 is concentrated along the width of the side wall 58 c of the leading anchor by the knife edge end 190 of the trailing anchor. This concentrated force is offset from the longitudinal central axis of the leading anchor 184. Therefore, the trailing anchor 182 applies torque to the leading anchor 184 tending to rotate the leading anchor in a counterclockwise direction, as viewed in FIG. 13, about an axis which extends through the location where the knife edge end 190 of the trailing anchor 182 engages the side wall 58 c of the leading anchor 184. Thus, the torque applied to the leading anchor 184 by the trailing anchor 182 tends to rotate the leading anchor about an axis which extends parallel to the flat outer side surfaces 30 c of the anchors and which extends along a linear line of engagement of the knife edge end 190 of the trailing anchor with the trailing end surface 68 c of the leading anchor.

Since the three outer corner portions of the leading anchor 184 are disposed in engagement with the cylindrical inner side surface 92 c of the guide member 82 c, in the manner illustrated in FIG. 3 for the anchor 10, the leading anchor 184 is restrained against rotational movement under the influence of torque transmitted from the trailing anchor 182 to the leading anchor 184. Thus, the leading anchor 184 is moved straight downward (as viewed in FIG. 13) under the influence of the force transmitted from the trailing anchor 182 to the leading anchor. The leading end surface 66 c of the leading anchor 184 applies force against the portion 106 c of the suture 12 c to pull the suture downward in the guide member 82 c.

As the anchors 182 and 184 are moved downward (as viewed in FIG. 13) together along the guide member 82 c under the influence of forces applied against the trailing anchor 182 by the pusher member 112 c, the leading anchor 184 moves through the open lower end portion 86 c of the guide member 82 c. As this occurs, the concentrated force applied against the trailing end surface 68 c of the leading anchor 184 by the tapered knife edge end portion 186 of the trailing anchor 182 causes the leading anchor to rotate in a counterclockwise direction, in the manner indicated by the arrow 140 c in FIG. 14. This results in the leading anchor 184 rotating about an axis which extends through the location where the knife edge end 190 of the trailing anchor 182 engages the portion of the trailing end surface 68 c of the leading anchor 184 disposed on the trailing end of the side wall 58 c of the leading anchor 184.

As the leading anchor 184 is being rotated under the influence of the torque applied against it by the trailing anchor 182, the trailing anchor continues to move straight downward (as viewed in FIG. 14) along the tubular guide member 82 c. As the leading anchor 184 is rotated in a counterclockwise direction, in the manner indicated by the arrow 140 c in FIG. 14, the leading end 66 c of the leading anchor moves rightward into the relatively soft cancellous bone tissue 76 c. The outer corner portion 22 c of the anchor 184 is leading. The wedge-shaped configuration of the outer corner portion 22 c of the leading anchor 184 facilitates movement of the leading anchor 184 in the cancellous bone tissue.

As this is occurring, the suture 12 is tensioned by pulling on the two portions 106 c and 108 c of the suture. This pulls the portion 106 c of the suture against the leading end surface 66 c of the leading anchor 184. The force applied by the suture 12 c to the leading end surface 66 c of the leading anchor 184 urges the leading anchor upward and toward the left (as viewed in FIG. 14) toward the tapered leading end portion 186 of the trailing anchor 182. The counterclockwise (as viewed in FIG. 14) rotation of the leading anchor 184 continues until the trailing end surface 68 c on the leading anchor engages the leading end surface 66 c on the trailing anchor 182.

After the trailing end surface 68 c on the leading anchor 184 has engaged the leading end surface 66 c on the trailing anchor 182, the pusher member 112 c pushes the trailing end surface 68 c of the trailing anchor 182 out of the guide member 82 c. As this occurs, the outer corner portions of the trailing anchor 182 move out of engagement with the cylindrical inner side surface 92 c of the guide member 82 c. Force transmitted from the suture 12 c through the leading anchor 184 to the trailing anchor 182 causes the trailing anchor to rotate and move leftward toward the position shown in FIG. 15.

As this is occurring, the leading anchor 184 continues to rotate under the influence of the force applied against the leading anchor by the suture 12 c. As the suture 12 c is tensioned, the two anchors 182 and 184 are rotated together through the position shown in FIG. 15 to the position shown in FIG. 16. When the anchors 182 and 184 reach the position shown in FIG. 16, the outer corner portions 22 c of the anchors engage the lower end surface 86 of the guide member 82 c and are embedded in the soft cancellous bone tissue.

The force applied against the two anchors 182 and 184 by tensioning the suture 12 c presses the leading end surface 66 c on the tapered leading end portion 186 of the trailing anchor 182 firmly against the trailing end surface 68 c on the anchor 184. At this time, the flat outer major side surfaces on the anchors 182 and 184 press against the soft cancellous bone tissue and the outer corner portions of the anchors 182 and 184 are engaged by the soft cancellous bone tissue to stabilize the anchors 182 and 184 in the same manner as previously explained in conjunction with the embodiment of the invention illustrated in FIGS. 1-6. Therefore, the anchors 182 and 184 are disposed in stable abutting engagement with each other and are held against movement relative to the bone tissue 72 c.

When the anchors 182 and 184 have been installed in the body tissue 72 c, as shown in FIG. 16, the guide member 82 c and pusher member 112 c are withdrawn from the body tissue. At this time, the anchors 182 and 184 have longitudinal central axes which are skewed relative to each other and slope upward (as viewed in FIG. 16) in opposite directions toward the outer side surface of the body tissue 72 c. Tensioning of the suture 12 c presses the leading end surface 66 c on the trailing anchor 182 firmly against the trailing end surface 68 c on the leading anchor 184. The two anchors 182 and 184 become wedged together and span the opening in the body tissue 72 c to strongly resist pulling out of the anchors 182 and 184 and the suture 12 c from the body tissue 72 c.

Since the anchors 182 and 184 slope upward (as viewed in FIG. 16) toward the outer side surface of the body tissue 72 c and away from each other, pulling on the suture 12 c results in the anchors becoming wedged even more firmly in the body tissue. The fore applied against the inner side surfaces of the anchors 182 and 184 by pulling on the suture 12 c tends to further embed the trailing end portion of the trailing anchor 182 and the leading end portion of the leading anchor 184 in the body tissue. Pulling on the suture 12 c tends to center the two anchors 182 and 184 across the opening through which they were inserted into the body tissue 72 c.

In the embodiment of the invention illustrated in FIGS. 13-16, the anchors 182 and 184 both have the same general polygonal construction as the anchor 10 of FIG. 1. However, it is contemplated that the anchors 182 and 184 could have a different construction if desired. Thus, the anchor 182 and/or the anchor 184 could have a cylindrical construction.

Plural Anchors—Guide and Pusher Members

In the embodiment of the invention illustrated in FIGS. 13-16, the anchors 182 and 184 are randomly oriented relative to the guide member 82 c. It is contemplated that it may be desired to orient the anchors 182 and 184 relative to the body tissue 72 c before the anchors begin to move into the recess 78. In the embodiment of the invention illustrated in FIG. 17, the guide member is constructed so as to retain the anchors in a selected orientation relative to the guide member as the anchors move axially through the guide member. In addition, the pusher member is constructed so as to apply a concentrated force against a selected portion of the anchor. Since the embodiment of the invention illustrated in FIG. 17 is generally similar to the body of the invention illustrated in FIGS. 13-16 and since the guide members and pusher members are constructed in a manner which is generally similar to the embodiment of the invention illustrated in FIGS. 7-10, similar numerals will be utilized to designate similar components, the suffix letter “d” being associated with the numerals of FIG. 17 to avoid confusion.

In the embodiment of the invention illustrated in FIG. 17, the tubular guide member 82 d has a cylindrical outer side surface 88 d with a cylindrical inner side surface 92 d. In addition, the guide member 82 d has a locating rib 142 d which orients the anchors 182 d and 184 d in the guide member 82 d. The locating rib 142 d extends along the inner side surface 92 d of the guide member 82 d for the entire length of the guide member.

The locating rib 142 d has a flat inwardly facing locating surface 144 d. The flat locating surface 144 d is disposed in a plane which forms a chord to the cylindrical inner side surface 92 d of the guide member 82 d. The locating surface 144 d has an axial extent which is the same as the axial extent of the guide member 82 d.

The locating surface 144 d engages the flat outer side surface area 30 d on the trailing anchor 182 d and the flat outer side surface area 30 d on the leading anchor 184 d. This enables the locating surface 144 d to position the anchors 182 d and 184 d in a predetermined orientation relative to the guide member 82 d. Thus, the corner portions 22 d of the anchors 182 d and 184 d are disposed diametrically across from the locating surface 144 d. The locating surface 144 d engages the flat outer side surface areas 30 d on the anchors 182 d and 184 d to hold the anchors in a predetermined orientation relative to a longitudinal central axis of the guide member 82 d.

A pusher member 112 d cooperates with the guide member 82 d to apply force against the trailing anchor 182 d at the corner portions of the trailing anchor. The pusher member 112 d is a cylindrical tubular member having a radially extending slot 150 d which extends throughout the length of the pusher member and receives the locating rib 142 d. The manner in which the pusher member 112 d cooperates with the guide member 82 d is the same as previously explained in conjunction with the embodiment of the invention illustrated in FIGS. 7-10. However, the pusher member 112 d does not have a tapered leading end portion corresponding to the tapered leading end portion 116 a (FIG. 8) of the pusher member 112 a. If desired, the pusher member 112 d could be provided with a tapered leading end portion.

The pusher member 112 d cooperates with the trailing anchor 182 d and leading anchor 184 d and the guide member 82 d to position the anchors 182 d and 184 d in the same manner as previously explained in conjunction with the embodiment of the invention illustrated in FIGS. 13-16. By using the locating rib 182 d, a surgeon can determine the orientation of the anchors in the body tissue 72 d by positioning the guide member 82 d relative to the body tissue 72 d in an orientation corresponding to the desired orientation of the anchors 182 and 184 d to the body tissue.

Plural Anchors—Guide Member—Third Embodiment

In the embodiment of the invention illustrated in FIG. 17, the guide member 182 d is provided with a locating rib 142 d to locate the anchors 182 d and 184 d relative to the body tissue 72 d. In the embodiment of the invention illustrated in FIG. 18, the guide member is provided with a plurality of longitudinally extending grooves which locate the anchors relative to the body tissue. Since the embodiment of the invention illustrated in FIG. 18 is generally similar to the body of the invention illustrated in FIGS. 13-17, similar numerals will be utilized to designate similar components, the suffix letter “e” being associated with the numerals of FIG. 18 to avoid confusion.

The guide member 82 e has a cylindrical inner side surface 92 e. In accordance with a feature of this embodiment of the invention, the guide member 82 e is provided with three spaced-apart and parallel longitudinally extending locating grooves 202, 204, and 206 (FIG. 18). The locating grooves 202, 204, and 206 extend axially throughout the length of the guide member 82 e and are spaced equal arcuate distances apart about the cylindrical inner side surface 92 e of the guide member 82 e. Thus, the locating grooves 202, 204 and 206 are spaced approximately 120° apart.

The corner portions 22 e, 24 e and 26 e on the anchor 182 e engage the guide grooves 202, 204, and 206 in the manner illustrated in FIG. 18. Although only the corner portions 22 e, 24 e and 26 e for the trailing anchor 182 e are shown in FIG. 18, it should be understood that the leading anchor, corresponding to the leading anchor 184 of FIG. 13, has corner portions which engage the guide grooves 202, 204, and 206 in the same manner as do the corner portions of the trailing anchor.

The pusher member has not been shown in FIG. 18, it is contemplated that a cylindrical pusher member, similar to the pusher member 112 of FIGS. 8 and 9 may be used to apply force against the trailing end surface 68e of the anchor 182 e (FIG. 18).

Plural Anchors—Second Embodiment

In the embodiment of the invention illustrated in FIGS. 13-16, the anchors 182 and 184 are formed separately from each other. This requires a surgeon to properly align and thread the anchors on the suture 12 c in the manner illustrated in FIG. 13. In the embodiment of the invention illustrated in FIGS. 19 and 20, a connector portion is provided to interconnect the two anchors. The connector portions retains the anchors in the proper orientation relative to each other and facilitate threading of the suture through the two anchors. Since the embodiment of the invention illustrated in FIGS. 19 and 20 is generally similar to the embodiment of the invention illustrated in FIGS. 13-16, similar numerals will be utilized to designate similar components, the suffix letter “f” being used in conjunction with the numerals of FIGS. 19 and 20 to avoid confusion.

An anchor 182 f (FIG. 19) has the same construction as the anchor 182 of FIGS. 13-16. An anchor 184 f has the same construction as the anchor 184 of FIGS. 13-16. In accordance with a feature of this embodiment of the invention, the anchors 182 f and 184 f are interconnected by a connector 220 which extends between the two anchors 182 f and 184 f. The connector 220 has a length which is coextensive with the width of side walls 58 f of the anchors 182 f and 184 f.

The anchors 182 f and 184 f have side walls 58 f with flat outer side surface areas 30 f which are disposed in a common plane. In addition, the anchors 182 f and 184 f have outer corner portions 22 f which are axially aligned with each other. The outer side surface areas 30 f on the side walls 58 f of the anchors 182 f and 184 f are maintained in alignment with each other by the connector 220. In addition, the connector 220 maintains the outer corner portions 24 f on the anchors 182 f and 184 f in alignment with each other.

Since the two anchors 182 f and 184 f are interconnected by the connector 220, the tapered leading end portion 186 f of the trailing anchor 182 f always faces toward the trailing end surface 68 f of the leading anchor 184 f. Therefore, when a suture 12 f (FIG. 20) is threaded through the anchors 182 f and 184 f, the anchors are always in the proper orientation relative to each other.

When the anchors 182 f and 184 f are installed in body tissue, in the manner illustrated in FIGS. 13-16 for the anchors 182 and 184, the connector 220 is deformed to enable the leading anchor 184 f to move from the orientation shown in FIG. 19 to the orientation shown in FIG. 20 relative to the anchor 182 f. Thus, when the anchors 182 f and 184 f have been moved to their installed positions relative to each other, in the manner illustrated in FIG. 20, the connector 220 is bent so that the leading end surface 66 f on the anchor 182 f and the trailing end surface 68 f on the anchor 184 f are disposed in abutting engagement.

The connector 220 is a web which extends along the leading end portion of the outer side surface 30 f in the side wall 58 f of the anchor 182 f and along a trailing portion of the outer side surface 30 f of the side wall 58 f of the anchor 184 f. The relatively thin web forming the connector 220 is integrally formed with the two anchors 182 f and 184 f. Thus, the two anchors 182 f and 184 f are formed as one piece having the configuration of an equilateral triangular prism. The leading end surface 66 f on the anchor 182 f and the trailing end surface 68 f on the anchor 184 f are formed by making a notch in the one piece prism. The notch does not extend completely through the side walls 58 d so that the thin web of the connector 220 remains to interconnect the two anchors 182 f and 184 f.

Although it is preferred to form the anchors 182 f and 184 f from a single piece of material with a thin web or connector 220 between the two anchors, it is contemplated that the anchors 182 f and 184 f could be formed from two separate pieces of material and interconnected by a separate connector 220. If this was done, the connector 220 could be formed of a material which is different than the material of the anchors 182 f and 184 f. For example, the connector 220 could be formed of a suitable polymeric material and bonded to the leading end surface 66 f of the anchor 182 f and to the trailing end surface 68 f of the anchor 184 f. If this was done, the polymeric material could be ruptured or broken as the connector 220 is deformed during installation of the anchors 182 f and 184 f and movement of the anchors to the orientation shown in FIG. 20.

It is also contemplated that the connector 220 could be formed by a plurality of relatively thin elements which are disposed at spaced apart locations along the leading end of the flat outer side surface 30 f of the side wall 58 f of the anchor 182 f and the trailing end of the flat outer side surface 30 f of the side wall 58 f of the leading anchor 184 f. The thin spaced apart connector portions could be integrally formed with the anchors 182 f and 184 f or could be formed of a suitable connector material which extends between the anchors and used to interconnect them, such as spots or small bodies of adhesive.

CONCLUSION

In view of the foregoing description, it is apparent that the present invention provides a new and improved method and apparatus for securing a suture 12 in body tissue. An improved suture anchor 10 has a polygonal cross-sectional configuration with an outer side 14 which is formed by a plurality of flat side surface areas 28, 30, and 32 which are interconnected by outer corner portions 22, 24, and 26. The anchor 10 has a passage 18 formed by a plurality of flat inner side surface areas 48, 50, and 52 which are interconnected by a plurality of inner corner portions 40, 42 and 44. The suture 12 is engageable with one of the inner corner portions 40, 42 or 44 to urge an outer corner portion 22, 24, or 26 of the anchor 10 into engagement with body tissue 72. A groove 162 may be provided in the end and/or outer side of the anchor to receive the suture.

A plurality of anchors 182 and 184 having the configuration of the anchor 10 or a different configuration may be used to anchor a suture. When a plurality of anchors are used, the suture 12 is inserted through each of the anchors and the anchors are sequentially moved into the body tissue. As a leading anchor 184 is moved into the body tissue, the suture 12 is tensioned to move a corner portion 22 on the leading anchor into engagement with the body tissue. A connector 220 may be provided between each anchor.
